Have you searched for your problem: polite answer: i wouldn't be using THIS template if i hadn't
If so, what terms did you try: pretty much tried every combination. nada answers, only questions.
State the nature of your problem: serious, see the below image.
Do you have a test account for us: sure, do you want my user/pass?

How exactly did you upgrade ? Using the changed files package ? Did you run the update script after uploading the files in the changed files package ?
Backup all the files and the database before upgrading.
If you have no MODs installed,
Download the changed files package from the downloads page.
Extract this package's contents to your hard disk.
Extract the zip file contents which is relevant for your board version (ex. if its from 2.0.4, then 2.0.4_to_2.0.11.zip) to your hard disk, and upload those files, and the 'install' folder into the root forum folder directory.(overwriting files)
Point your browser to the ../install/update_to_2011.php
Delete the 'install' and 'contrib' directories.

DLinkOZ followed those steps pretty much exactly.

I get this error randomly and almost contantly whenever i'm logged in.
The only way i can get around it is to delete temp internet files, close ALL IE windows and wait a bit.

I'm not sure but maybe 2.0.11 doesn't like cable modem ISPs like shaw cable that hop proxies?? Anyways, is there some chart that tells me what "1020" error is caused by?

There's our problem. They state it's fixed in 4.1.8, so I'll do an upgrade and we'll see if it goes away.

*Edit*
Just craptacular... 4.1.8 isn't released yet. 4.1.7 is still the stable build...

A workaround I found was to change the table type on the phpbb_sessions table to myisam instead of heap. The downside, it's not as fast as it requires a disk write for session data whereas heap is stored strictly in memory. Upside? I don't believe either of our boards generate enough traffic to be impacted by this whatsoever. I've upgraded mine and it seems ok so far. Let me know if you'd like to try this as well. Btw, I did a manual copy of all the db data files about 20 minutes ago, so I can offer a very recent backup should anything go awry.

This is an error with mysql 4.17. Either upgrade or change your session table to myisam. Another fix is to get more people on the site as it only happens when there is a single session in the heap table. :D
